The data-portion of the RX02 is what a PeeCee FDC can't digest. It *might* be possible to program an Amiga to digest RX02 disks (it also lacks a dedicated FDC - it uses a 4096-bit shift register in the sound chip to import the data, and (for MFM formats) miniterms applied by the graphics co-processor to translate back and forth to plain binary data). The Catweasel should be able to handle it, but, as has been hashed out here before, you'd have to roll your own with it; the software support is severely lacking compared to the capability of the hardware.
